Background Information for Students

Background for GeoTools Community

Sample Idea to cut and Paste

h3. Lite Swing Example

GeoTools used to have a StyledMapPane viewer that a lot of people used as an
example when creating their own Applications (and Applets - remember GeoTools
is old). This example was dropped after years of neglect (it was not updated
to an OGC compliant CoordinateReferenceSystem implementation if you must know).

Can you *please* over the course of the summer make us a new "lite" example.
We are excited by the idea of the Spring RCP framework (so you could test your
component there), but the example should be "lite" enough to work as an applet.

JMagick integration.

JMagickis an open source Java interface ofImageMagick. It is implemented in the form of Java Native Interface (JNI) into the ImageMagick API. Jmagick has proven to be very fast and quite stable with jpeg and png files especially when compared to imageio plugins.

It would be great to try and hide JMagick behind imageio-ext (some work has already been done in this direction in order to later expose imageio-ext plugins as geotools plugins. 

MrSID and ECW plugins based on gvSIG JNI wrapper.

gvSIG has direct JNI wrapper for ECW and MrSID. Even if the license is not fully compatible with the geotools one it would be nice to provide a few imageio-ext plugins to expose this capabilities in geotools afterwards.

GCP Support in GeoTiff plugin.

It would be nice to add support for Ground Control Points in the GeoTools geotiff plugin. This would mean doing some refactor of the current plugin. We could also port the work performed last year by Jan during the SoC 2007 on warping into geotools trunk.

KML Reader / Writer support

 see email here

Raster polygonalization

 It would be great to have some raster-to-feature algorithm in geotools. GeoSolutions has some old code to contribute  but probably it would be worth investigating a new approach. There is plenty of documentation out there on this task.

WCS Client library

It would very useful for the users to have a GeoTools client library for WCS similar to the ones for WMS and WFS. They could retrieve raster sub-datasets for processing or visualization on GeoTools based clients.

Image mosaicking/pyramid plugins handling tiles within JDBC database

A Christian Mueller proposal

Inspired form Oracle Spatial Raster, ArcSDE and the geotools file based image plugins I decided to develop a geotools plugin for image mosaicking and pyramid handling/storing georeferenced tiles in a jdbc database.

As prerequiste work I wrote a python utility for tiling images and retiling already tiled images (it produces tiled images and a shape file for georeferencing). This utility was contributed to the gdal project http://www.gdal.org/gdal_retile.html

The basic idea is to have a spatial table storing the georeferenced tile info and a data table storing the image data in encoded form (formats supported by JAI).
It should also be possible to use only one table storing both kinds of information. There is one master table holding the info for all coverages/pyramids. Each entry in this table can reference his own spatial/image table.
Since there are many naming conventions in different enterprises, all table and attributenames are configurable using a xml file. DB Connect configuration (JNDI or standard) is also configurable.

Not included is an import utility. Import jobs for different databases are individual, perhaps we should document some samples.

Emergency Response or MIL2525B Symbols

There are additional "well known" symbols besides those mentioned in the Style Layer Descriptor specification, it would be very valuable to make the Emergency Response and MIL2525B symbol sets available to the community.

Here is an RnD page: Custom Symbols for MIL2525B and EmergencyResponse


Acceptance Letter

The following is a Sample Letter for Mentors to send out - we need to cover the following points:

All of these should be links to the developers guide ...
